It seems that when people get a Diamatrix, they then reserve the Matrix for oxide use. The higher fractal dimension of the Matrix loves to retain oxides. The Chemistry is better for oxides, too.
For example, I doubt anything could beat Matrix/Chrome Oxide for sunstone.


I haven't tried it since the green CrOx is messy...but the Matrix with cerium oxide is super fast with sunstone and such a glassy finish.

Which oxide do you recommend on it for quartz? Also, I have some nice sunstone on the way, I'll try one on the Matrix and one on the Diamatrix and see how it goes.

Personally I prefer the cerium oxide BATTStik on the Matrix for quartz. I go right from cutting on a 1200 sintered lap to the Matrix with CerOx. I get a faster and finer finish than I get with a Diamatrix and 100K BlackStik on quartz. I've polished a table on a 20 x 16 mm amethyst that way with perfect results.

The zirconia battstik is specifically geared towards quartz, IIRC. Among traditional faceting oxides (cerium, AlOx, CrO (CrOx?)), cerium is generally considered the best for quartz.

I'm loving the zirconium Battstik on this year's premaster competition stone, which is quartz, which I am hating. Can't wait to finish and move on.

For Feldspar, I have polished it quickly to a high finish with the Refractory Alloy Battstik on the Matrix.

Just my 2 cents worth...

Using Gearloose's CrOx Stik is incredibly easy and mess-free. I used it for some time on Darkside with excellent results and very little greenness anywhere. In fact, the Darkside holds it so well that I haven't even worn the tip off the Stik, though truth be told it probably was used for only a couple dozen stones before I switched to Greenway.

The Greenway has been my absolutely favorite polishing lap (GreenWing actually). I add a bit of the CrOx Stik to it with stubborn or large facets but very rarely.

And yes, I still haven't worn the tip off it yet. But my faceting productivity has been near zero the last year. :)

FWIW, and it should be plenty, my first try at the Diamatrix was with a 30 x 22 Uruguayan amethyst (cushion). I tried the Zirconia with a little mist from a spray bottle, medium speed, from 1200 sintered. Insanely fast. Facets look like they are wet.

Since then, I really haven't found anything the Zirconia does not work well with. Amazing product!

being tempted by the concept of the diamatrix I am nevertheless concerned by cross contamination especially for the BATT only side.

And I wonder how I can polish a girdle for which I usually are on the very outside of the lap. Unless having something big on the dop the polishing area would be unreachable.

Only solution I see is to just let it remain on the pre polish state.

For the girdle, the pre polish of 8000 or 3000 is plenty good enough.

I keep a small band of 100,000 on the very edge of the back side of my diamatrix.

I also use the back with 13k and 100k. But I left a gap between the 13k and the edge, so I could keep it for polishing girdles.

That said, I often stop at the 13k stage and call it good enough. But for my wife's stuff, she gets the full 100k. Nieces and my daughter, 13k is good enough.

looking at the Gearlose site if I am not wrong the Diamatrix is a harder Matrix and the one with Matrix polishing area incorporated into a BATT is the Dominatrix.

Using a 8" disc what would be the min. angle to still reach the Matrix surface ? Or otherwise what is the diameter of the Matrix part (in mm if possible)

That early photo of the Dominatrix needs to be replaced. All Dominatrixes are made with the DIAmatrix center, for more versatility with the harder stones like sapphire, topaz, crysoberyl, and moissanite, though it is still useful for damond or oxides on softer stones.

Hi Jon,

whats the diameter of the Diamatrix on the 8 " and 6" Dominatrix ? For Quarz Diamatrix is less recommendable than Matrix right ?
